37" Philips LCD no sound.

Maybe the antenna that you are using is not picking up sound from the channels. It could also be the cable. If it makes a humming noise, it means that the speakers are getting electric current and that they SHOULD be okay. It also could be your tuner. Maybe check it all out at some tech place like best buy. Those guys can help

My lcd tv makes a humming noise

Try removing all cables going to the TV except the power cord. Power on the TV and press mute. If you have any unwanted noise, then you have a defective TV and since it is new, you should get an exchange. If there is no noise with the A/V cables removed, then you might have hooked the source (cable box/DVD Player) into the wrong inputs of the TV.

In most cases it's the Cable issue. Either bad Cable Box or the Wires are not grounded properly. Disconnect the Audio Cables or the COAX cable from the Cable Box and see if the Humming noise goes away.

Hum in the audio - 32'' Proscan 1080i

does the hum occur when playing a dvd or only when watching tv ? if the hum occurs only when watching tv, i would like you to disconnect the cable line from either the wall or the back of the cable box and see if this hum disappears. if the hum disappears call your cable company. you have what is called a " 60 cycle ground loop ". hope this helps.

More often than not, the humming sound on any electronic device is brought about by the AC side of the power supply not only of the device itself but also all other equipment it is attached to. In your particular case, it maybe introduced into the system from:
  • (coaxial) cable TV leadin;
  • connections of DVD, VCR, game consoles and others;
  • electrical noise from lamp dimmers, lights with electronic ballasts, wireless phones.
It is interesting to note, that the noise could be from other appliances plug in the same circuit as the TV, you of course could try plugging it into another outlet or branch. In some instances, you could even try filtered regulators similar to those used by desktop computers.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
